The B7013 is a short link road in the Ayrshire town of Dalmellington.
The road starts at a roundabout on the B741 in the town centre and heads east along the High Street. It follows a valley to end at a T-junction on the A713 about half a mile later. The road is S2 for its entire length and seems more rural than urban, except at its west end.
It is difficult to tell exactly, owing to the scale of the map, but when first shown on the 1939 10-mile map, the B7013 appears to follow the current route of the A713, with that route still running through Dalmellington, as it did in 1922. However, as the 'bypass' route predates 1922 (although it was unclassified at that time), it is possible that this is a mapping error, and that the A713 was moved out, with the town road being renumbered in sequence, suggesting that it dates back to the late 1920s. Alternatively the B7013 may have been the first number given to the bypass and the two roads could have swapped numbers by the 1940s.
